Original application: filed February.6,',191'1, Serial No. 606,922.-DiVide d and this application filed August 5, 1914. Serial No. 855,283:

T0 (ZZZ whom it may, concern:

Be it known that I, SYDNEY As'roN M'nnsny ROSE, formerly residing atWaldorf Chambers, Aldwych, in the city of NVestminster, London, England,but now residing at 79 Elgin avenue, Maida Vale, London, England, asubject of the King of Great Britain and Ireland, have invented a i newand useful Improvement. in Recording- Targets, of which the following.is a speci fication.

This invention relates to recording targets, and more particularly tothe recorders or indicators for use with targets of that type in which aflexible strip is passed overa series of contacts, one or more of whichoperates, as the perforation effected by a shot passes over same, toestablish an electric circuit for actuating the recorder or indicator.

My present invention consists in certam improvements in the means forrecording or indicating the position of the shots on the targets.

In my co-pending application filed 6th February, 1911, Serial No;606922, I have described the electrical system employed for recordingthepositions of the shots and this divisional application is directed tothe construction of the indicator mech anism. p

In the accompanying drawings: Figure 1 illustrates in side elevation anindicator constructed accordingto this invention, and Fig. 2 is a planview partly in section of the indicator. Fig. 2 isa detail sectionalview showing the construction of the pivot bearing appearing in Fig. 2.Fig. 3 is a side elevation to an enlarged scale of the mechanism forreleasing the turn-table of the indicator hereinafter described, andFig. i is a view on thelinenr-w in Fig. 3 and looking in the directionof the arrows. Figs. 5 and 6 are detail views of the indicator releasingmechanism. Figs. 7 and 8 are plan views showing different positions ofcertain parts of the indicator mechanism. Fig. 9 is a view in sideelevation showing a detail of construction hereinafter described.

The indicator comprises an instrument 0 similar to a galvanometer andhaving a pointer c which is attached to the wellknown moving coilrotatable within the magnet 70. This magnet is fixed upon a table Zwhich, in the construction illus trated, is, by way of example, circularin form and is provided at its periphery with teeth Z which mesh with aworm c on the spindle c. The table is pivotally mounted upon a stand Zand has attached to it one end of a spring Z the other end of which isfixed to the said stand. The spindle 0 is supported at its inner end ina bearing 0 carried by an arm 0 controlled by a spring 0 whichnormallycauses the worm c to engage with the table Z. The outer end of thespindle 0' is furnished with the pulley 0 which is driven as describedin my said co-pending application from the main target, and thls endofthe spindle is carriedin a bearing 0 which is pivoted in a support '0mounted upon one wall of a casing 4n. 7 which incloses the; instrument.

Adjacent to the table Z and at rightangles to the spindle 0 is a stand 0furnished at its upper end with two spring arms n, a each in the form ofa flat spring and arranged at right-angles to each other longitudinally.The spring arm 'n, is provided at its outer end with a projection orcatch 0 and the spring arm n is likewise furnished with a projection nadjacent to the projection 0 The arm n is provided with a secondprojection '12, which extends downwardly into thepath of a lug orextension Z mounted upon the table Z. In addition to the extension Z thetable is provided. with a spring finger Z which extends some littledistance beyond the table Z, and with an armZ of such a length that whenthe table is in itsnormal positionthis arm presses the spring arm noutwardly. The table Z and; its accessories are mounted withina casing mfurnished with a translucent disk m arranged opposite to the pointer 0and marked: to correspond with the representation to be fired at on thetarget at the butt.

A shot having been fired at the target at the butt and the flexiblestrip having been set in motion as described 111 my said application,the pulley 0 will be rotating and revolving the spindle 0 so that thelatter rotates the table Z in the direction of the arrow in Figs. 2 and7. The pointer c of the instrument 0 mounted upon the table Z will thustravel horizontally across the duplicate target m corresponding with thetravel of the main target until the travel of the latter is stopped,whereupon the electric current flows through the instrument and causesthe pointer 0 to move in a vertical plane. To return the pointer to itsnormal position the flexible strip at the target is again set in motion,with the effect that the rotation of the table is continued in thedirection of'the arrow in Figsp2 and 7.

This continued rotation of the table brings the spring finger Z againstthe bearing 0 which it presses until the extension Z passes beneath theprojection n and raises the spring arm a. When the springarm a is thusraised the upper end of the arm carrying the bearing 0 is released fromits catch- 0 and the bearing 0 pushed away'by means of the spring fingerZ so as to release the worm 0 on the spindle 0 from the table. While thetable has been rotating in this direction the spring Z has been wound,and immediately the worm c is released from the table the said springrotates the table in the opposite direction, thus returning the pointerto its normal position. To prevent the too rapid return of the table Z adash-, pot p is provided. During the return movement of the table thereturn of the bearing 0 is prevented by means of the projection n on thearm 01?, as shown in Fig. 8, and when the table has nearly reached theend of its return movement the arm Z on the table engages with andpushes out the arm 119,

- passes through the casing and is adapted to be rotated by a head 7".The lever q is provided with two lateral projections g, g of which theformer engages with an inclined pin 9 upon the upper side of the springarm a. Assuming the table Z to have rotated to indicate the position ofa shot,

the spring arm Z will be pressing against the bearing 0 of the shaft 0.To return the indicator to its normal position the shaftr is rotated inthe direction of the arrow shown in .Fig. 9, whereupon the projection 9on the lever g raises the arm n and releases the bearing 0 from itscatch 0 with the result that the spring 1* disengages the worm c fromthe table Z. The table new returns under the influence of the spring Zto its normal position; but the return of the bearing 0 of the shaft 0is arrested by the other projection g on the lever g. The table havingreturned, the shaft 7' is released and the leverq returned under theinfluence of the spring 9 thereby releas-' ing the shaft-bearing 0 andpermitting the worm Q3 to reengage the table Z.

What I claim is 1. In indicators for recording targets, th

combination, with a pointer, of a rotatable turning the table and meansoperated by said table for reengaging the worm with its teeth.

2. In recording target indicators, the combination with a pointer and arotatable table carrying the same, of a worm-shaft for rotating saidtable, a spring-controlled bearing atone end of said shaft, a spring armon said table which serves at the end of the travel of the table in onedirection to disengage said worm-shaft from the table, means forreturning the table, a catch which 7 holds said shaft in its disengagedposition and an arm which on the return of the table releases said shaftand permits it to re engage with said table.

In witness I have hereunto set my hand in the presence of two witnesses.
